Did anyone get the sense the article was dancing around the main point with vague language? They left it ambiguous about whether they meant effectively all charging should switch to the day or a portion should switch (to give some kind of optimal balance). I haven't looked at the model but it seems really odd to think that there shouldn't still be some night charging, to soak up the fixed capacity that's there to cover variations in solar/wind.
